TRIMMINGS COITVEYER FOR SEVV'ING MACHINES.

Application filed March 28, 1925.

An object of my invention is to provide means for conveying the trimmings from a sewing machine to any desired place.

Another object of my invention is to pro vide in a sewing machine means for removing the waste material trimmed from the fabric as it is sewed together.

Another object of my invention is to provide means to be attached to a sewing machine for conveying the trimmings to any desired place as they fall from the trimmer, and thus prevent said trimmings from fall ing on the floor.

Havingthus stated some of the objects of my invention, a brief description of the diiierent figures in the drawings will now be given.

Figure 1 is a plan view of my device;

Figure 2 is a frontelevation of my device, showing the vertical swing of the mouth-- piece in dotted lines as at 13;,

Figure 3 is an enlarged section showing the hinge which permits vertical and lateral movement of the mouthpiece;

Figure 4 is a plan view of asection of the mouthpiece, showing the manner of at-- tachingto a sewing machine;

Figure 5 is a perspective view of my device, showing it attached to a sewing ma chine.

Having thus briefly described the various figures in the drawings, a more detailed description of the drawings will now be given, in which like reference characters represent corresponding parts throughout the drawingsp My device is adapted to be attached to the table on which the sewing machine rests, and to swing into position to catch the trimmings.

The numeral 1 indicates the main tube of my device, which is shown here in vertical position. This vertical tub has a projection 2 made integral therewith, with holes 3 therein for securing the device to the table on which the sewing machine is mounted. To attain this mounting, bolts will be inserted thru the holes 3 and screwed into the table 35.

Located at approximately right angles to the main vertical tube 1 is the mouthpiece 4 which is connected to the vertical portion by a hinge 5, which is composed of the projections 6 and 7 the projection 6 being integral with the mouthpiece 4., and

' surface of the said tubular member.

Serial No. 19,048.

the projection 7 being integral with the vertical tube 1. These project-ions have holes through them, the projection 6 having the hole 23, with the slanting face 24 on the right hand side thereof, and the projection 7 having a hole therein, the upper portion of which is boredto fit the body portion 22 of the member 8, and the lower portion being of greater bore to fitthe enlarged portion 20 of the member 8. Thus .it'will be seen that the shoulder 21' on the member 8 its against the shoulders formed by the reduced bore in the projection 7.

The portion 22 of the member 8 has a coiled spring 17 mounted thereon, which spring is held in position by the nuts 18, 18 which serve to regulate the tension of said coiled spring.

The member 8 has an enlarged end 20 which prevents the member 8 from being pulled through the hole in the projection 7 when tension is applied by means of the nuts- 18.

The upper right hand portion of the member 1 has a cut away portion 9, which has side walls 10 shaped to fit against the sides of the slanting section 12 of the mouthpiece 4;

On the side of the member 1 opposite the hinge 5 means are provided for holding the mouthpiece i in adjusted and operating position. These means consist of the following. A pin 14 is secured in a hole drilled in the side of the tubular member 1. This pin projects outwardly from the exterior A leaf spring 13 is secured to the wall portion of the mouthpiece 4 by means of rivets 16. This leaf spring has a hole 15 therein through which the pin 14 projects when the device is in operating condition.

The lowermost portion of the slanting portion of the mouthpiece is indicated bv the reference numeral 19. This point is well within the hollow portion 11. of the member 1, and has its end shaped in the form of an arc of a circle of the same dimensions as the hollow portion of the member 1. r i 1 Y The manner in which this device is fitted to a sewing machine is best illustrated in Figures 4 and 5. The intake end of the member 4; is indicated by the reference numeral 25. This portion rests upon the lower trimmer blade 34:. This end 25 has a guide lip 26 which fits slightly behind the lui) end of the trimmings deflector 30. To enable this guide lip to fit behind the end of the trimmings deflector the foot guide 36 has a portion 37 thereof filed away, and the guide lip 26 fits in this cavity filed in the foot guide.

The sewing machine arms are indicated by the reference numeral 28, while the press er foot is shown as at 29, and the opening in 29 is indicated by the reference numeral 31. The movable blade is indicated by the numeral 32, while the cutting edge of the stationary blade is indicated by 33. The curved portions of the mouthpiece are indicated by the reference numeral 27.

The method of operation of my device is as follows: The device is mounted 011 the table, with the mouthpiece swung back to the position shown in dotted lines in Figure 1. IVhen it is desired to have this conveyer operate the mouthpiece is again swung on its hinge 5 and it is swung into the position shown in Figures 4 and 5. The vibration of the lower trimmer blade upon which the mouthpiece rests, which is mounted in the presser foot will cause the mouthpiece to vibrate vertically as shown by the dotted lines in Figure 2. The fabric will be trimmed by the machine, and instead of falling down onto the table and becoming mixed with the finish goods, and also falling on the floor and becoming soiled, will be directed into the end 25 of the mouthpiece 4, and will be carried to the slanting portion 12, and then will proceed to fall into the vertical hollow space 11 or the interior of the member 1. A waste basket placed beneath the lower end of member 1 will catch this waste or trimmings coming from the sewing machine.

It might be stated that the lower portion of the member 1 may be made curved and jointed to allow the lower portion thereof to be swung from one waste basket to another, when the color of the fabric being sewed is changed. This would avoid different colors of trimmings being conveyed to the same container.

In the drawings I have shown a preferred embodiment of my device, it being understood that any constructional changes may be made in the device, provided-such changes fall within the scope of the appended claims.

What I desire to protect and secureby Letters Patent is:

1. Means comprising a vibrating trough member connected to a vertical pipe member for conveying trimmings from the trimmer of a sewing machine to a point removed from the table on which the sewing machine rests.

2. In a sewing machine, means comprising a vibrating trough member connected to a vertical pipe member located in close proximity to the trimmer for receiving and conveying the trimmings from the sewing machine to a point removed from the trimming means, said means being operated by the presser foot of the sewing machine.

3. In a sewing machine, a vertical hollow member, a horizontal spout member hingedly connected to the vertical hollow member, means on the end of the spout member for receiving trimmings from the sewing machine, said means cooperating to direct and convey said trimmings to the vertical hollow member.

at. In a trimmings conveyer, a vertical hollow portion, a spout portion hingedly supported on said vertical hollow portion, the said spout portion being adapted to receive the trimmings as they leave the trimmings deflector of a sewing machine, and convey said trimmings through said spout and into the vertical hollow portion.

5. In an attachment for sewing machines, a vertical hollow member, a trough-like member hingedly and removably mounted at approximately right angles to the vertical hollow member, and connected to the hollow member, a tension spring in the connection between the two members, the trough-like member resting on the lower trimmer blade and vibrating with the said lower trimmer blade, said trough-like member positioned to receive the trimmings from the sewing machine and to deliver said trimmings to the vertical hollow member.

6. In a conveyer ,for trimmings from a sewing machine, conveying means comprising a vibrating trough member connected to a vertical pipe member adapted to be swung into operating position, and to be swung out of operating position at the will of the operator.

7 In .an attachment for sewing machines. means comprising a vibrating trough member connected to a vertical pipe member adapted to engage the end portion of the trimmings deflector to convey trimmings emanating from said end portion of the trimmings deflector.

8. In a sewing machine, trimmings conveying means secured to the table on which the sewing machine is mounted, a portion of thesaid trimmings conveying means resting on the lower trimmer blade. r

In witness that I claim the foregoing as my own, I hereby aliiir my signature.

JOHN H. VAUGHN.
